Description

Technical Field

[0001] The utility model relates to the technical field of copper-aluminum joints, in particular to a copper-aluminum joint with high bonding strength. Background Art

[0002] The copper-aluminum joint is a joint that connects two different metals, copper and aluminum. Since it is composed of two materials, copper and aluminum, and the copper-aluminum joint is a special connection method, appropriate materials and processes are required to ensure the quality and stability of the connection.

[0003] When combining existing copper-aluminum joints, the same holes are usually opened on the surfaces of the two joints, copper bolts are inserted, and then nuts are used to fix them so that the two joints are connected. However, for joints connected by simple bolts, when the two joints are swung relative to each other with the fixed point of the bolt connection as the center, looseness will occur between the bolts and the nuts. This low bonding strength will make the joints prone to poor contact, so a copper-aluminum joint with high bonding strength is needed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a copper-aluminum joint with high bonding strength.

[0005] The utility model is implemented by the following technical scheme: a copper-aluminum joint with high bonding strength, comprising a main body mechanism, an embedding mechanism is arranged on the right side of the main body mechanism, and a connecting mechanism is arranged inside the main body mechanism;

[0006] The main body structure includes a first joint, a first hole groove is opened on the top of the first joint, a first gasket is arranged on the top of the first joint, a first wire pressing nose is fixedly connected to the left side of the first joint, a slot is opened inside the first joint, a connecting groove is opened on the inner wall of the slot, and a second gasket is arranged at the bottom of the first joint.

[0007] Through the above technical solution, the first joint is a copper-aluminum transition joint, and part of the joint is made of copper, while the part close to the first wire crimping nose is made of aluminum. This type of joint can effectively prevent the different chemical properties of copper and aluminum during connection. Electrochemical corrosion may occur when they are in direct contact, resulting in a decrease in the performance of the joint.

[0008] As a further improvement of the above solution, the first gasket and the second gasket are of the same size.

[0009] Through the above technical solution, an opening-like slot is provided on the right side of the first joint, and two round hole-like slots are opened on both sides of the slot to connect with the second joint.

[0010] As a further improvement of the above solution, two connecting grooves are provided, and the two connecting grooves are symmetrically distributed with the slot as the center.

[0011] As a further improvement of the above scheme, the embedding mechanism includes an insertion plate, which is inserted into the inner wall of the slot, a second connector is fixedly connected to the right side of the insertion plate, an insertion rod is fixedly connected to the left side of the insertion plate, a second hole groove is opened on the top of the insertion plate, and a second wire pressing nose is fixedly connected to the right side of the second connector.

[0012] Through the above technical solution, when the plug plate is inserted into the slot inside the first joint, the plug rod will also be inserted into the connecting groove as the plug plate goes deeper, and the right end of the plug plate is semicircular, which can achieve a good limiting effect with the slot when inserted into the plug plate. When the two joints are connected, the second hole groove of the first hole groove on their surface will also overlap. At this time, the bolt is inserted and the nut is tightened to complete the connection of the two joints, achieving a high bonding strength.

[0013] As a further improvement of the above solution, the shape of the plug plate corresponds to the slot, two plug rods are provided, and the size of the second hole slot is the same as that of the first hole slot.

[0014] As a further improvement of the above solution, the connecting mechanism includes a bolt, which is arranged on the inner wall of the first hole groove, and a nut is threadedly connected to the surface of the bolt.

[0015] Through the above technical solution, the materials of the bolts and nuts are both copper.

[0016] As a further improvement of the above solution, the material of the bolt is the same as that of the first joint and the second joint.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model has the following steps: when the plug plate is inserted into the slot inside the first joint, the plug rod will also be inserted into the connecting groove as the plug plate goes deeper, and the right end of the plug plate is semicircular, and when inserted into the plug plate, it can well achieve a limiting effect with the slot. When the two joints are connected, the first hole groove and the second hole groove on their surfaces will also overlap. At this time, the bolts are inserted and the nuts are tightened to complete the connection of the two joints. This connection method achieves a high bonding strength through the limiting effects of the plug plate and the slot, and the plug rod and the connecting groove.

[0019] The utility model adopts a copper-aluminum transition joint as the first joint, and the material of the joint part is copper, while the part close to the first wire crimping nose is aluminum. This joint can effectively prevent the different chemical properties of copper and aluminum during connection, which may cause electrochemical corrosion when they are in direct contact, resulting in a decrease in the performance of the joint.
